CONDENSER AND FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 485,031, dated October25, 1892.

Application filed August 23,1892. $erial No.443,856. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES GROHMAN, of Garteret, in the county ofMiddlesex and State of New Jersey, have invented a new and ImprovedCondenser and Feed-Water Heater, of which the following is a full,clear, and exact description.

My invention relates to improvements in surface steam condensers andfeed water heaters; and the object of my invention is to produce aneflicient and simple condenser which will also operate as a feed-waterheater.

To this end my invention consists in certain features of constructionand combinations of parts, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in both the views.

Figure 1 is a vertical longitudinal section of the apparatus embodyingmy invention, and Fig. 2 is a vertical cross-section on the line 2 2 inFig. 1.

The condenser is provided with a main case 10, having a suitable base tosupport it, and this case has near one end and on the under side awater-inlet 11 and an outlet 12 at the top, although the conditions maybe reversed, as hereinafter described, so that the steam may be let intothe top and the water of con densation pass out of the bottom. The caseis provided on the bottom with several handholes 13, which enable it tobe easily cleaned out, and extending longitudinally through the lowerportion of the case is a perforated spreader-plate 14, through which thewater must pass to the tubes above, and it also serves as a check to thedirt which enters with the water, causing the same to be retained on theunder side of the plate, where it may be easily cleaned out through thehandholes. Arranged longitudinally in the case are groups of tubes 15and 16, through which steam or water may pass, as hereinafter described.The inlet ends of the tubes 15 are arranged immediately opposite theinlet 17 in the upper portion and at one end of the case, and the tubeshave a downward inclination and lead into a chamber 18 at the oppositeend of the case. From this chamber 18 the lower group of tubes 16 leadsto a chamber 19,

which is arranged immediately below the inlet 17, and the tubes 16 areinclined downward so that the steam or water may flow quickly throughboth the tubes 15 and 16, and thus afford no chance for stagnant waterand nothing to induce rapid rusting. From the chamber 19 opens an outlet20; but in every instance the openings to the case may be used as eitherinlets or outlets, as desired. Immediately beneath the opening 12 is ahollow deflector 21, which also serves as a feed-water heater, and thisdeflector is curved upward in the center, as shown at 22, so that whensteam is permitted to enter the opening 12 it will be deflected to bothends of the case 10. The deflector is supported by bolts 23, which aresecured to the case-top and engage lugs 2% 011 the ends of thedeflector; but the deflector may be supported in any convenient way. Thedeflector is provided on one side and at opposite ends with inlet andoutlet pipes and 26, which lead outward through the case and are adaptedto connect with a water-supply and with a boiler in the usual Way.

When the condenser is used simply as a condenser and without referenceto heating the feed-water, the opening 11 is connected with. a source ofcold-water supply and the openings 17 and 20 serve as an inlet andoutlet, respectively, for steam and condensed water. When the water ispermitted to enter the inlet 11, it is spread by the plate 14 and passesupward through the perforations of the plate, so as to strike and coolall the tubes 16 and 15, the water passing out at the top through theopening 12. It will thus be seen that the steam which enters the inlet17 and passes through the tubes 15 and 16 will be rapidly condensed andthe condensed water will run freely out of the outlet 20.

hen the condenser is used to serve the double purpose of a condenser andfeed-water heater, the conditions are reversed. In this case the coldwater is permitted to enter the inlet 17 and fiowthrough the tubes 15and 16 and out through the outlet 20, thus making the tubes cold. Thesteam connections are then made so that the steam will enter the opening12 and pass down between the tubes 15 and 16 and the steam will becondensed by contact with the tubes and the water will pass out throughthe opening 11. The feed-water is permitted to enter the hollowdeflector 21 through'the pipe25 and it passes out through the pipe 26;but'as the steam which enters the case strikes the deflector before itis condensed by contact with the tubes the deflector will be keptconstantly hot and the feed-water will be well heated.

From the foregoing description it will be.

seen that the condenser and feed-water heater is of very simpleconstruction, and that "it may be made to perform one or both of thefunctions described, as desired.

Having thus described my' invention, I" claim as new and desire-tosecure 'by Letters Patent 1. The.combination,with the maincase having-.openingsfor steam or Water connectionsat the top andbottomand'the-condensing; tubes -extending longitudinally throughthe casean'dhaving-an inlet and 'outlet independ above'thetu'bes,"th'e"deflector being curved u'pwarda-t a point beneath the topopening of the case, and feed-Water pipes connected with 3 5 thedeflector, substantially asdescribed.
